To all whom it mag concern:

Be it known that '1', RHonA C. HARRIS, a citizen of the United States, residing at Pittsburgh, in. the county of Allegheny and State of Pennsylvania, have invented certain new and useful lmprovementsin Tire- Protectors, of which the following is a speci fication, reference being had therein to the accompanying drawing.

Thls mventlon relates to tlre protectors and the principal object of the same is to provide a protector which has a plurality of sections which are flexibly connected together so that they may conform to the contour of the wheel and to form each section from a number of frames which are carried one within the other, the inner frame carrying the tread blocks and the anti-slipping plates.

By formingthe protector as described in the following specification the tread blocks are securely held in place but, at thesame time, may be very easily removed when it is desired to repair or renew them.

The invention is illustrated in the accompanying drawings, .wherein Figure 1 is a side elevation of one portion of a wheel having the improved protector mounted thereon. Fig. 2 is a perspective view of one of the sections, one of the tread bloc-ks being removed from the outer frame.

Fig. 3 is a perspective View of a slightlymodified type'of section. Fig. 4 is aperspective yiew of still another type of section. Fig. 5 c is a perspective view of a modified 'form of section in which a frame and tread blocks similar to the inner frame and tread blocks shown in Fig. 4 are used without an outer frame. Fig. 6 is a view of the frame and tread blocks shown, in Fig.

5, with one of the side bars removed. Fig. 7 is a view of the frame shown'in Fig. 6 with the treadblocks removed. Fig. 8 is a perspective view ofthe frame shown in Fig.

7 with the side bars removed. Fig. 9 is a- .perspective view of a modified form of section. Fig. 10 is a section through the outer frame of the sectlon shown 1n Fig. 9. Fig.

'11 is a section through thefinner frame shown in Fig. 9. Fig. 12 is a section through the tread block used in the type shown in Fig. 9. Fig. 13 is a perspective view of a type of section which is somewhat similar to that shown in Fig. 4. Fig. 14 is a view of the tread block and inner frame used in Fig. 13. Fig. 15 is a. perspective view of still another type of section. Fig. 16 is a perspective view of the'inner frame used in the type shown in Fig, 15. .Fig. 17 is a perspective view of the tread block used in Fig. 15. Fl 18 is a perspective view of a tread block slmilar to that shown in Fig. 17 'with the anti-slipping deyices removed.

- Fig. 19 is a fragmentaryviewof the outer frame used in Fig. 15. Referring to the accompanying drawings by numerals it will be seen that the invention comprises a number of formsof sections which are held together and secured to the tire so that the tread of'the use will not touchthe ground but will be -incl sedby the sectlons'thus doing away with any danger';

of puncturing the tire.

In Fig. 2 I have shown one type of sec- 'tion whichmay be used and which comprises side bars-20 and 21which are connected by the end bars'22j and 23, and also by the intermediate bar 24, the side bars 20 and 21 being carried downto the bottomof The end bars 22and 23. are each provided with a'centrally located seat 25 inwhich a link 26 is mounted so that theprotector' can be connected with the wheel. This type. of section is intended to be uscdwith wheels in which thetir'e is formed of'two sections, thus necessitating two rows of tread blocks. The cross bar 21 divides the outer frame into two sectionsand the inner frame 27 is mounted in each of the sectionsand carries atread block 28. The two' frames and the tread block converge toward their outer faces so thatthe inner-frames and tread blocks will be held in place when the protector is upon the wheel without necessitating any other securing means.

' In Fig. 3 I have shown aslightly modified form of protector from that shown in Fig. 2 in which there are provided two separate sections instead of one section provided with cross bar 2 1. The side bars 29 and end bars 30 are constructed similar to the ones shown in Fig. 2 and the inner frame .31 and tread block 32 are also similar to those shown in Fig. 2. I

It should be noted however that the inner frame and tread blocks extend the full length the cross bar 24: to strengthen the cross band.

ble fastening which holds the sections togetherand assists in -holding the protector upon the wheel' In ,Fi- I 4 through 8,'I havei'shown a 'slightly modified t ype of section in which the outer frame 36 has its end walls pr0-' vided with recesses 37 in'which the securing 38 are mounted. The inner frame -which'is used with this type of section com:

prises a curved base 39 and converging'end' 7 walls l0. The side walls e1 are secured to- :theihase and-the end walls and the treadblocks- 42; are positioned in the, inner j frame and rest: upon -the basefbetweenthe end walls.-- The tread blocks and-end walls con- 1 verge towardthe outer face of the protector so Ith at'when the second side wall 43 is secured to'the base and end walls by means of I, "the screwse A, the tread blocks will begsecurely held in place. ,Antislipping fplates 45*are' placed'between the treadblocks so exactly similar to the one shown in Fig. 4 I and the tread block 52 issimilar to theone thatthe wheels will be prevented vfrom sl'n'd- ,gring and also to prevent the read blocks ombeing worn too fast; If desired the outer. frame maybe omitted andthe inner frame provided with'bloc-ks with which the] securing cable isv connected,

'In Figs, 9 through 12, I have shown a type or section in which the outer frame 30- s very similar to the frameshown in Fig. fwith the exception of the projection 47 I which is formed at each end so that the atching .1ink48 may be connectedwith the I e. The inner frame l9 is similar to the er frame 'shownin Fig. 3 and the tread blo clri 50 is also similar tothe block used in ",FigZ 3, theqinner frame being the full length of the "opening forrned in the outer frame and. (the tread block being a solid piece, In Figs; 13 and 14 the outer frame 51 is shown in Fig. 9. The inner frame comthe screw 54iand' has diverging arms 55 extending fromeach end whichextend up the prises a plate 53 which is secured to the mnen-face of the-tread blockf by means of' side faces of thetr'ead block. These arms 4 55 hold the anti-slipping plates 56 to the side faces of the tread blockso that there is no danger of them slipping out of place.

In. Figs. l5 through l9 I have shown: a

modification in which the outer frames 57 are provided with end ears 58 to which the links 59 are connected. The frames 57 are connected by links 60 and are heldin lace by: the. spacing block 61, the spacing lock When using the device the sectionsare connected together and placed around the wheel-andtheend sections are connected together by 'any suitable means so that the string of sections will be securely held upon the wheel. a a

What I claim is:

an inner frame having a curved base, end' walls extending'fromsaid base, side walls secured to said base and end walls, treadv blocks carried by said inner flame, and-- means connecting said seetions' together.-

2. A protectorcompnsmg a plurality of inner frame moimtedjn' said' outer frame, sald lnner frame comprlsln'g-a curved base,
